ATTACHMENT FOR STOVES.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed December 10. 1906. Serial No. 347.118. Renewed October9. 1907. Serial No. 396.665.

To all whom it may concern:

Be it known that I, ARTHUR H. MERRILL, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inAttachments for Stoves, of which the following is a specification.

This invention relates to attachments for stoves, ranges and otherheaters, and has for its object the provision of an improved portableappliance which may be readily placed in 1posltion upon the stove orother heater, as wil be hereinafter set forth.

As is well known the odors from the kitchen will frequently permeateanentire dwelling, and this is especially observable when fats are beingmelted, or vegetables having quantities of essential oils of odoriferouscharacter are being cooked. It has long been a desideratum to provide afully-operative attachment which will prevent any and all diffusion ofdisagreeable odor, and which will always act properly in accordance withthe laws of nature, and which may be sold on the market, and readilyplaced in position on the stove or other heater.

By my invention an attachment is provided which consists of a shell ofmetal either open at the front or closed by a door of any kind ascircumstances may require, and which will be connected by a fine orflues with the draft-space in the heater leading to the chimney,the'shell being so constructed that no odor can bedisseminated therefromwhen the device is in use.

In the accompanying drawings, Figure 1 is a side elevation of anordinary stove with my attachment applied thereto. Fig. 2 is atransverse sectlon of the top of the stove illustrating the mode ofoperation of the attachment, and also showing said attachment intransverse section. Fig. 3 is a plan view of the attachment, and Fig. 4is a view of an ordinary stove-lid, the central opening of which isgenerally covered by a small supplemental lid, and lIl-WhlCll openingwhen said supplemental lid is removed the shell of the attachment may beplaced.

Like numerals designate similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates in a general way acooking-stove which may be of any approved type, or may be in the formof a gas range, or any other kindof heater, connected to a chimney, thecharacter of the heating appliance being immaterial so far as thepresentinvention is concerned.

A usual pipe or conduit 2 for the products of combustion leads to thechimney of the heater in the customary manner.

Designated in a general way by the numeral 3 is my improved attachmentcomprising in the present instance a shell 4 of metal and shown providedwith an open front 13 which may be closed by a door if desirable.Leading from any suitable point on the shell 4 are pipes or conduits 5shown as of elbow construction. Two of these pipes 5 are illustrated andthey serve when inserted in the stove-lids to steady the shell and tohold it rigidly in place.

In the top of the stove are the usual openings covered by lids ofordinary character, the one employed. in the present case for thevent-pipes 5 of the attachment being represented in Fig. 4, anddesignated by the numeral 6, said lids having each a central opening 7which may be closed when the attachment is not in use by the ordinarysmall supplemental lid (not shown). In the present construction a pairof these perforated lids is illustrated at the rear of the stove, and toplace the attachment in position, all that itis necessary to do is toinsert the ends of the vent-pipes 5 into the openings 7 of said lids.

To illustrate the operation of the inven tion a skillet 8 is shown inposition in one of the ordinary openings on the top of a stove or otherheater, and the products driven off from said skillet will pass in thedirection of the arrows, through the shell 1, and through the vent-pipes5 to the hot-air space 9 of the stove, suction being created, asindicated by arrows, in said hot-air space by the draft of the chimney,and said suction operating to draw inthe products passing from thevessel in which the article is being cooked to said chimney, as will bewell understood.

To prevent back-draft of the products emitted by the cooking or otheroperation, the top of the shell is preferably formed as a curved surface10 and at the front edges above the opening in the shell, the wall isdeflected and formed as a reentrant flange at 11, this constructionforming a kind of trap or pocket which will prevent any backdraft whilethe attachment is in use from carrying the odors or other products beingheated through the opening in the front of the attachment. Usual handles12 are attached to the shell by which it may be lifted from or placedupon the stove when desired.

Changes may be made in the form of the shell and in the constructionthereof to prevent the back-draft from carrying odors into the kitchenor'other room, and the vent flues for said shell may be differently disposed than in the manner set forth without departure from the invention.

Having thus described the invention, what I claim is 1. An attachmentfor stoves or other heaters, comprising a shell having an open front,and a curved top wall, said curved wall merging in a depending rentrantflange where it joins the open-front, and thus servsvazse ing as a trapto prevent the emission of odors, and a vent-conduit leading from saidshell and ada ted to communicate with the draft-space of said heater,and to secure the attachment upon the top of the heater.

2. An attachment for heaters comprising a shell having a curved top, andan open front joined to the top by a reentrant flange to prevent theemission of odors due to backdraft; and conduits leading from the shelland fitting in openings in the rear stove lids.

In testimony whereof I aflix my signature in presence of two witnesses.
